Experimental Human-Computer Interaction
by Helen C. PurchaseExperiments that require the use of human participants are time consuming and costly: it is important to get the process right the first time. Planning and preparation are key to success. This practical book takes the human-computer interaction researcher through the complete experimental process, from identifying a research question to designing and conducting an experiment, and then to analysing and reporting the results. The advice offered in this book draws on the author's twenty years of experience running experiments. In describing general concepts of experimental design and analysis she refers to numerous worked examples that address the very real practicalities and problems of conducting an experiment, such as managing participants, getting ethical approval, pre-empting criticism, choosing a statistical method and dealing with unexpected events.

Linux iptables Pocket Reference
by Gregor N. PurdyFirewalls, Network Address Translation (NAT), network logging and accounting are all provided by Linux's Netfilter system, also known by the name of the command used to administer it, iptables. The iptables interface is the most sophisticated ever offered on Linux and makes Linux an extremely flexible system for any kind of network filtering you might do. Large sets of filtering rules can be grouped in ways that makes it easy to test them and turn them on and off. Do you watch for all types of ICMP traffic--some of them quite dangerous? Can you take advantage of stateful filtering to simplify the management of TCP connections? Would you like to track how much traffic of various types you get? This pocket reference will help you at those critical moments when someone asks you to open or close a port in a hurry, either to enable some important traffic or to block an attack. The book will keep the subtle syntax straight and help you remember all the values you have to enter in order to be as secure as possible. The book has an introductory section that describes applications,followed by a reference/encyclopaedic section with all the matches and targets arranged alphabetically.

The Iconology of Abstraction: Non-figurative Images and the Modern World (Routledge Advances in Art and Visual Studies)
by Krešimir PurgarThis book uncovers how we make meaning of abstraction, both historically and in present times, and examines abstract images as a visual language. The contributors demonstrate that abstraction is not primarily an artistic phenomenon, but rather arises from human beings’ desire to imagine, understand and communicate complex, ineffable concepts in fields ranging from fine art and philosophy to technologies of data visualization, from cartography and medicine to astronomy. The book will be of interest to scholars working in image studies, visual studies, art history, philosophy and aesthetics.

The reader will need a good knowledge of master data management, information lifecycle management, data governance, data product design, data engineering, and systems architecture. Also required is experience of Big Data technologies such as Hadoop, Spark, Splunk, and Storm. What You Will Learn * Identify the need for a Data Lake in your enterprise context and learn to architect a Data Lake * Learn to build various tiers of a Data Lake, such as data intake, management, consumption, and governance, with a focus on practical implementation scenarios * Find out the key considerations to be taken into account while building each tier of the Data Lake * Understand Hadoop-oriented data transfer mechanism to ingest data in batch, micro-batch, and real-time modes * Explore various data integration needs and learn how to perform data enrichment and data transformations using Big Data technologies * Enable data discovery on the Data Lake to allow users to discover the data * Discover how data is packaged and provisioned for consumption * Comprehend the importance of including data governance disciplines while building a Data Lake In Detail A Data Lake is a highly scalable platform for storing huge volumes of multistructured data from disparate sources with centralized data management services. It eliminates the need for up-front modeling and rigid data structures by allowing schema-less writes. Data Lakes make it possible to ask complex far-reaching questions to find out hidden data patterns and relationships. This book explores the potential of Data Lakes and explores architectural approaches to building data lakes that ingest, index, manage, and analyze massive amounts of data using batch and real-time processing frameworks. It guides you on how to go about building a Data Lake that is managed by Hadoop and accessed as required by other Big Data applications such as Spark, Storm, Hive, and so on, to create an environment in which data from different sources can be meaningfully brought together and analyzed. Data Lakes can be viewed as having three capabilities--intake, management, and consumption. This book will take readers through each of these processes of developing a Data Lake and guide them (using best practices) in developing these capabilities. It will also explore often ignored, yet crucial considerations while building Data Lakes, with the focus on how to architect data governance, security, data quality, data lineage tracking, metadata management, and semantic data tagging. By the end of this book, you will have a good understanding of building a Data Lake for Big Data. You will be able to utilize Data Lakes for efficient and easy data processing and analytics. Style and approach Data Lake Development with Big Data provides architectural approaches to building a Data Lake. It follows a use case-based approach where practical implementation scenarios of each key component are explained. It also helps you understand how these use cases are implemented in a Data Lake. The chapters are organized in a way that mimics the sequential data flow evidenced in a Data Lake.
From Playgrounds to PlayStation: The Interaction of Technology and Play
by Carroll PursellHow technology shapes play in America—and vice versa.In this romp through the changing landscape of nineteenth- and twentieth-century American toys, games, hobbies, and amusements, senior historian of technology Carroll Pursell poses a simple but interesting question: What can we learn by studying the relationship between technology and play? From Playgrounds to PlayStation explores how play reflects and drives the evolution of American culture. Pursell engagingly examines the ways in which technology affects play and play shapes people. The objects that children (and adults) play with and play on, along with their games and the hobbies they pursue, can reinforce but also challenge gender roles and cultural norms. Inventors—who often talk about "playing" at their work, as if motivated by the pure fun of invention—have used new materials and technologies to reshape sports and gameplay, sometimes even crafting new, extreme forms of recreation, but always responding to popular demand.Drawing from a range of sources, including scholarly monographs, patent records, newspapers, and popular and technical journals, the book covers numerous modes and sites of play. Pursell touches on the safety-conscious playground reform movement, the dazzling mechanical innovations that gave rise to commercial amusement parks, and the media's colorful promotion of toys, pastimes, and sporting events. Along the way, he shows readers how technology enables the forms, equipment, and devices of play to evolve constantly, both reflecting consumer choices and driving innovators and manufacturers to promote toys that involve entirely new kinds of play—from LEGOs and skateboards to beading kits and videogames.

Why Brains Don't Compute
by Dale PurvesThis book examines what seems to be the basic challenge in neuroscience today: understanding how experience generated by the human brain is related to the physical world we live in. The 25 short chapters present the argument and evidence that brains address this problem on a wholly trial and error basis. The goal is to encourage neuroscientists, computer scientists, philosophers, and other interested readers to consider this concept of neural function and its implications, not least of which is the conclusion that brains don’t “compute.”
